Josh NZ Posted October 10, 2012 Share Posted October 10, 2012 Hi all, My series 2a has a leak somewhere in the braking system but I have no idea where due to lack of knowledge.. The brake pedal is damp and there is actually a puddle of fluid under it on the mat. It leaks visibly when the pedal is pressed hard, dribbling down the pedal shaft. Which component is leaking?? The brakes are still working well without any loss of efficiency except for maybe 5-10mm more travel in the pedal which has me really confused Thanks in advance!

secondjeremy Posted October 11, 2012 Share Posted October 11, 2012 As the slave cylinders are at the wheels and the master cylinder is above the pedal - its the master cylinder. If the master cylinder is leaking there is a high risk of total brake failure and the vehicle shouldn't be driven until properly repaired.

santalars Posted October 11, 2012 Share Posted October 11, 2012 Wow that sounds like a big leak! First, be careful and make sure that you refill the fluid reservoir. if it leaks that much - don't drive it. Second don't panic. relatively easy fix. One of the gakets/seals in your master cylinder has blown. (well or there is a leak from the reservoir, but this is very unlikely). Take the liknkage cover plate off (6 or 8 screws) and you can see the linkage from your pedal to the cylinder. ...and most likely you can now exactly see where it leaks. I don't know how comfortable you mechanically are but just to keep in mind that you have to make the call yourself if you want to work on your brake system or not. If you don't feel comfortable get somone who is from the trade. You need the get the cylinder out. You woul have to check with e.g. Repco if they have a Master cylinder kit available. It's sometimes amazing what Repco has in stock. You would then have to open the cylinder and replace the gaskets. How to do that in detail is probably best to look up in the workshop manual as I can't tell from the top of my head without taking it apart myself. If there is no kit available you would need to see if you either find a brake specialist - There is a guy on trade me who claims that he could do all brakes and parts- or get a new master cylinder, which is not expensive when you order in the uk. Whatever you do, be aware that you cant drive the car when the master cylinder is out -meaning it's stationary and it is dangerous to drive it now. getting the cylinder out and sorted is probably the best way forward. Be carefull not to break the brake line threads and start soaking them in WD40 tonight. Quote Link to comment Share on other sites More sharing options...
